So I just recently realized that despite the bulkiness, the individual switches of these Soviet Hall Effect boards, and those from the Honeywell Hall Effect boards are independent working units, i.e. completed with sensors and magnets. Unlike the construction on the modern Chinese Hall Effect board which managed to miniaturize the mechanism to the Cherry MX size by parsimoniously placing the sensors on the PCB.
If only the current one has independent individual working units, then DIY enthusiasts can potentially mess with many more things about the new GB purchase.
I like these individual sensing units better - perhaps that is reflecting why the US and Russia were the two major players in the cold war.
